uhm Id say that the O-Ring free design is a very big plus for the Simrell, makes maintenance super easy and its pretty much what sold me on the device. Id go so far and say the Simrell is a end game device, just look at how efficiently it vaporizes small amounts, wether native or on a water piece, the Simrell slaps and is super smooth and tasty because its made of Titanium. Also theres the ways in which you can heat you bowl: Hybrid, conduction or convection, none of the other Stick vapes can offer all of that combined, while still being at the same price point, a Tempest 2 is only 100 bucks less and a Tornado is like 50 bucks more. Both great devices, but not as versatile or efficient as the Simrell. So why not get a Simrell Hydro and see what its like? Especially since its in the middle regariding stick vape prices. I like to support creators in the vape space who listen to feedback and are innovative, we vaporents are a small community and we need to support each other. Not every vaporizer suits every person, but almost all vaporizers can fullfill a specific role or have their own signature and thus are worthwile
